Sex hormonal imbalance possible role in sexual orientation

According to the textbook by the Life Extension Foundation entitled “Disease Prevention and Treatment ” 5t Edition on page 608, pregnenolone -the “mother hormone”- is synthesized from cholesterol in the adrenal gland, and then through DHEA and the intermediate hormone androstenediol it cascades to produce both the male hormone testosterone and the female hormones collectively called the estrogens. According to the authors the estrogens are a mixture of 3 separate female sex hormones: Estrone,Estradiol, and Estriol in different proportions and with different functions
It occurred to me that maybe the difficulty for some individuals to determine their own gender and sexual behaviour may be the result of shifts in the concentrations of these different hormones.I recall in my own medical practice that I diagnosed a case of Kleinfelter’s syndrome based on the presence of an extra X (sex) chromosome-which incidentally was made in my own private Western Cytogenetic Laboratory.
